Abstract
A multidimensional database query engine processes a query request by forming a logical plan of subqueries for retrieving and assembling the data called for by the query request. A multidimensional database connector is invoked to transform a logical plan that defines and orders each subquery into a physical plan for accessing the data repositories where the data satisfying the query is stored. The query engine is invoked or called by an application and receives a query plan indicative of data repositories interrogated by query instructions in the query plan. For each data repository of the plurality of data repositories that may be interrogated by the query plan, a connector is defined based on commands for accessing each data repository. The connector associates each query instruction from the query plan with a corresponding repository command for accessing the data repository.
